Benefits of technology

The present invention is for a multimedia head unit in a vehicle that has two Bluetooth antennas and two receivers. One of the Bluetooth antennas can be dedicated to interfacing with additional devices, like an auxiliary unit. This allows for easy swapping of the auxiliary unit to add extra functions to the head unit without updating its electronic configuration. The auxiliary unit can provide navigation, satellite radio, Internet access, hands-free communication with a cell phone, and other capabilities that the standard head unit may not provide. Additionally, the use of an auxiliary unit allows for easily upgrading the head unit without changing its mounting position in the vehicle. The head unit can be flexibly configured even after manufacturing and shipping to a customer.

Problems solved by technology

However, replacing the head unit may be difficult, expensive, and may compromise the aesthetic appearance of the vehicle.
